Yes I did read that. Also read that if you take out the level plug and fill it up, it’s full once it starts running out. But I’ll just put 3.5 pints in it to be more accurate

Go by the level plug. The volume is an approximation.

:Dito: Level plug is most accurate.

Yep! And have a drip pan under to catch the overfill! I always seem to add the gear oil slowly at first, taking forever. Then I get impatient and dump a bunch in, at which time it ALL comes pouring out the full level hole!!

Gonna get some more 80-90 gear oil to put in it tonight. Thinking I might buy a cheap oil to run through it to clean the water out. Hope my bearings are ok!


Good. I find using kerosene works well; diesel would also work to flush out the tranny box. Fill to proper level, drive around a bit, drain. Can repeat with fresh kerosene another time or two until you're satisfied it's clean. Might also cut a new gasket for the shifter plate.



Fill full of diesel (or kerosene) or had some with the oil?

Not sure where my reply went lol but, do I put some oil in with the diesel or just run it with diesel to clean the water out of the tranny

Hi,
The experts on here have said before, use just the kerosene or diesel, without oil. Fill it to the level plug hole, and then drive it around for 5 minutes. I would drive it in 3rd gear, that throws more fluid around in the housing. You can drain it, and repeat, if the fluid looks bad when draining.

Below is a pic of what it looks like under the shifter cover. :)

I use off-road diesel. Cheaper that kero or auto diesel. 3.5 pints only. If you use more, it will leak out the seals and make a real mess.

Seems like for a half gallon (rounding up 3.5 pints for easier math) it wouldn't make a whole lot of difference dollar wise. Basically half the difference in the price of a gallon of "on road" diesel or kerosene vs "off road" diesel.
I think your going to spend more cleaning up the mess with whichever you use than you'll save using off road. :D :wink:

Hey guys, so I’m installing my new choke lever on the carb and I have the screw tight on the lever but I can still pull it off of the rod on the carb. Am I missing something? Thanks

If it is an old, used choke lever, the threads can become stripped and you cannot get it tight enough on the choke shaft. But if it is new, then there is an issue somewhere.

Hi,
If it is the original style lever, like in the pic I posted on page 1 of this post, the screw has to bend the sides of the lever together, to tighten it on the shaft. You might need to turn the screw tighter to bend the metal together. A 90 degree, ratcheting screwdriver works to get more turning power. But the shaft has to be the right size, if it is too small, then the shaft needs replacing probably.
I think the shafts have a sort of splined area for the lever to grip onto. :)

If you have already tightened the securing screw down and the lever still comes off the shaft, you might try a thin file in the slit of the lever to allow it to clamp tighter. Just a thought.

The lever is new that I bought from McDonald carb. I will get a ratcheting screw driver to see if I get it tighter. The style of the lever looks exactly like the pics posted on here.
